In order to manage your Lyric thermostat remotely via the Lyric app, you will need to connect the Lyric thermostat to your in-home Wi-Fi network. The Configuration section of your Lyric app will guide you through this step. If your thermostat is having trouble locating your Wi-Fi network, you may want to try these troubleshooting tips:
If you live in an area with many Wi-Fi networks broadcasting in the same space, it's possible that your thermostat did not find your network on the first scan. You will need to refresh the network list by pressing the "Refresh" button on your Lyric app screen and try connecting again. If pressing "Refresh" does not work, change the channel your router is broadcasting on. Please consult your router's manual for instructions on changing the channel.
Check that your router is broadcasting the Wi-Fi signal at the appropriate Radio Frequency range. Lyric only operates in the 2.4GHz range. This is why your thermostat may not be able to see the network while your smart phone (which operates in both the 2.4 and 5.0 GHz range) sees the network just fine.
Most dual-band routers can broadcast two networks, one network on the 5GHz radio and one network on the 2.4GHz radio. You will need to ensure that the 2.4GHz radio network is enabled on your router. Please consult your router's manual for instructions.
Note: If you have chosen to use a non-broadcasting SSID (network name) on your router, your network name will not appear on the Lyric Wi-Fi list. You will need to manually add your router using the "+" button at the bottom of your Lyric app screen.
